assignToHttpClientWithSecureOptions static method

void assignToHttpClientWithSecureOptions(
  1. HttpClient httpClient,
  2. List<ProxySettings> proxies, {
  3. dynamic host,
  4. SecurityContext? context,
  5. bool onBadCertificate(
    1. X509Certificate certificate
    )?,
  6. void keyLog(
    1. String line
    )?,
  7. List<String>? supportedProtocols,
})

Assign http client connection factory to proxy connection.

Applies host, context, onBadCertificate, keyLog and supportedProtocols to SecureSocket if connection is tls-over-http
